That's number one on my reading list right now, followed by The Giver. I'm basically just picking random books from Wikipedia's list of dystopian literature.
While not normally a huge fan of most dystopia, the Giver is quite excellent in my opinion. I remember my mother reading that one to me when I was little (that would have been around when I was 10 though), and the fact I can actually remember most of the book as read to me by her counts as high praise. It's one of only a small handful I remember in so much detail.
If you like it, there are apparently 3 more books (the fourth came out last year, just finding out about it now). I've read the next one, Gather Blue a few times, and it is easily my favourite of the three I read, and I think I need to read Messenger (#3) again, as I've forgotten too much of it now. Once I'm back up to speed, I need to read Son.
And speaking of books that were read to me that I really enjoyed, the Dark is Rising series (fantasy) is one of my two favourite series from childhood, along with the Shadow Children series (dystopian).
